<p><code>as</code> implements all the standard SH64 opcodes.  In
addition, the following pseudo-opcodes may be expanded into one or more
alternate opcodes:
</p>
<dl compact="compact">
<dt><code>movi</code></dt>
<dd><p>If the value doesn&rsquo;t fit into a standard <code>movi</code> opcode,
<code>as</code> will replace the <code>movi</code> with a sequence of
<code>movi</code> and <code>shori</code> opcodes.
</p>
</dd>
<dt><code>pt</code></dt>
<dd><p>This expands to a sequence of <code>movi</code> and <code>shori</code> opcode,
followed by a <code>ptrel</code> opcode, or to a <code>pta</code> or <code>ptb</code>
opcode, depending on the label referenced.
